1 Claim.

;nected at the suction side thereof to a, collecting trough in the housing so that a small quantity of the liquid may be used and re-circulated.

Another object of this invention is to provide in a devic of this kind an improved rotary or centrifugal filter disposed in the sump so that the heavy or solid particles will be retained in the sump, and the filter screen will not become clogged.

A further object of this invention is to provide a device of this kind which is simple in construction and can be used for articles of various sizes and shapes.

A further object of this invention is to pro vide an improved method of removing paint which includes subjecting the article to a spray or mist of a paint removing characteristicin a closed chamber for a period of time. sufficient to dissolve the paint.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawings,

Figure 1 is a detail side elevation, partly broken away, of a paint removing device constructed according to an embodiment of this invention,

Figure 2 is a fragmentary plan view of the device with the top cover removed,

Figure 3 is a transverse section taken vertically through the device; and a Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure 2.

Referring to th drawings, the numeral Ill designates generally a housing which is mounted on a supporting frame H. The frame II in-- clude upright legs l2 connected together adjacent the lower ends thereof by longitudinal connecting bars l3 of angle-shape and the end legs are connected together by end angle bars I4.

The frame also includes a pair of longitudinal or side angle bars I5 providing the support for the housing H1. The housing [2 is formed of a bottom wall l6, side walls I1, and end walls I8. The bottom wall I6 has secured thereto a longitudinally extending trough [9 which communi- 2 Q cates at one end thereof with a sump ,20. A screen 21 is disposed across the upper end of the trough [9, being secured to a screen frame 22. The housing II] has extending'lengthwise thereof a manifold pipe 23 which extends over the top of the screen. 2!. The pipe or manifold 23 has secured thereto a plurality of laterally extending branches 24 with which upwardlyextending nozzle pipes 25 are connected.

Each nozzle pipe 25 has secured thereto a lower nozzle 26 and an upper nozzle 21. The manifold or pipe 23 also has secured thereto upright end nozzle pipes 28 having a lower nozzle 29 and an'upper nozzle 30 secured thereto. The manifold pipe 23 extends outwardly through one end of the housing It and in the present instance extends through the sump 20 and is connected to a pipe 3| which is connected to the outlet side of a pump 32 operated by a motor 33. Th pipe 3| has interposed therein a valve 34 and a T 35 is also interposed in the pipe 3| between the valve 34 and the pump 32.

A discharge valve 36 is connected to the T 35 so that when it is desired to remove'the cleaning fluid from the system, valve 34 may be closed and valve 35 opened and th cleaning fluid then discharged into a receptacle or the like. The

sump 20 is provided with a removable cover 31 and a suction pipe 38 connected at one end to the suction side of the pump 32 is connected to the lower portion of the sump 20.

In order to provide for filtering the fluid which is removed from the sump 20, I have provided a cylindrical filtering screen 39 which is secured to a shaft 40. The shaft 40 extends through a housing 4| which is fixed to the pipe 38 and the shaft 40 is operated by means of a motor 42 connected to the shaft an through an endless belt 43.

In the use and operation of this device, the article from which the paint is to be removed is placed in the housing [0 between the side nozzles 26 and 21 and the end nozzles 29 and 3|]. These nozzles may be directed on different angles, as shown in Figure 2, so that substantially the enby the pipe 38and will then return to the housing l0 through the pipe 3|. As the fluid passes through the sump 20 into the pipe 38, this fluid Will pass through the rotary filter 39. The filter 39 being of cylindrical configuration will provide for centrifugally removing the solid particles from the screen so that this filter will not become clogged by such solid particles.

It will be understood that this device will operate for a suflicient length of time to dissolve the paint, varnish or other finish on the article and that the fluid used will be any suitable paint or varnishing removing fluid.

I do not meanto confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What I claim is: 7

Paint removing apparatus comprising a rectangular housing, an elongated longitudinally extending drainage trough carried by said housing, a sump at one'end of said housing communicating with one end of said trough, a longitudinally extending manifold within said housing, pairs of opposed lateral spaced apart branches connected to said manifold and extending along a portion of the length thereof, upstanding nozzle pipes carried by each of said branches and the oppo- EDWARD E.
